Favourite Led Zeppelin album?

Anything from Led Zep I - Physical Graffitti I suppose. None of those albums as a whole do much for me, but each has at least one iconic song on it. At a push as it is one I have been enjoying recently Houses of the Holy.

edit: Also awaiting delivery of The Song Remains The Same (remastered) so could be that next week.

When I was at uni we used to get wasted in a mate's room in hall (with a towel at the bottom of the door) and this was always on the turntable, never got changed. We just kept turning it, listened to it over and over. When I moved in with my friend into her house we got a massive poster of the sleeve art that entirely covered one wall on the landing. We'd probably be arrested for that now :/
